In an extensive memoir-almost a complete treatise--on "Dynamical Systems with Two Degrees of Freedom" (Trans. Amer. Math. Soc., 18 ; 1917), he reduced all problems relating to such systems, even in the 'irreversible' case, to the problem of determining the orbits of a particle ...

and of course tulips. They flourished in Pennsylvania too, where in 1698 William Penn received a report of John Tateham's 'Great and Stately Palace,' its garden tull of tulips. By 1760, Boston newspapers were advertising 50 different kinds of mixed tulip 'roots.' ...
We study the behavior of orbits in two different galactic dynamical models,describing the motion in the central parts of a triaxial elliptical galaxy with a dense nucleus.Numerical experiments show that both models display regular motion together with extended chaotic regions.A detailed investigation of...

(The Secret of the Universe)41, Kepler hypothesized that the orbits of the six known planets corresponded with six spheres, five circumscribing the five Platonic solids and one inscribing the smallest. To test his hypothesis, Kepler became mathematical assistant to Tycho Brahe in 1600 and gained...
